Here is the discussion that happened when FIRST changed the rules so that the top 8 seeds could pick each other. Previously, the top 8 couldn't pick another team in the top 8, like TierraDelDiablo proposed for the second option.
Remember, these are people reacting to the change, I'm still trying to find a thread that talks about it past tense.
